Oh no! Boris the cat has awakened from his nap and found he has the wrong shadow. It is, in fact, a mouse's shadow—Vernon the mouse's, to be specific. But since Vernon has felt very important and imposing, toting Boris's shadow around all day, he isn't in a big hurry to give it back. Full of funny asides and unexpected turns for readers up to 8, Leigh Hodgkinson's shadow play is exuberantly illustrated with collage materials and cartoon characters that remind us of Lauren Child's Charlie and Lola books.
